"For myself, I was bitterly opposed to the measure [the annexation of Texas], and to this day regard the war [with Mexico] which resulted, as one of the most unjust ever waged by a stronger against a weaker nation. It was an instance of a republic following the bad example of European monarchies, in not considering justice in their desire to acquire additional territory... The Southern rebellion was largely the outgrowth of the Mexican war. Nations, like individuals, are punished for their transgressions. We got our punishment in the most sanguinary and expensive war of modern times."
— Ulysses S. Grant, *Personal Memoirs of U. S. Grant*, 1885
